+# Adapter `bert-base-uncased_sentiment_sst-2_pfeiffer` for bert-base-uncased
+
+Adapter in Pfeiffer architecture trained on the binary SST task for 20 epochs with early stopping and a learning rate of 1e-4.
+See https://arxiv.org/pdf/2007.07779.pdf.
+
+
+**This adapter was created for usage with the [Adapters](https://github.com/Adapter-Hub/adapters) library.**
+
+## Usage
+
+First, install `adapters`:
+
+```
+pip install -U adapters
+```
+
+Now, the adapter can be loaded and activated like this:
+
+```python
+from adapters import AutoAdapterModel
+
+model = AutoAdapterModel.from_pretrained("bert-base-uncased")
+adapter_name = model.load_adapter("AdapterHub/bert-base-uncased_sentiment_sst-2_pfeiffer")
+model.set_active_adapters(adapter_name)
+```
+
